I would like to begin a discussion of sites which are an excellent source of related links for sites in the "green" niche: forums, directories and blogs. Please let us all be respectful of these sites and the important purpose we share by not spamming any of them. Rather, let us take the opportunity to spread the message of sustainability by utilizing sources which permit some site promotion. Please stay on topic and only mention sites specific to the green niche which accept dofollow link submission or sig links. I will begin: greenauthors.com (social bookmark) ecofirms.org (directory) greenmaven.com (search engine) Next? If you have a long list of dofollow forums, blogs or directories in this niche, please link to it rather than posting giant lists here.
